In this blog, you will get all you wanted to know about mandrel pipe benders, let’s discover now!
What is A Mandrel Pipe Bender?
A mandrel pipe bender is a highly specialized machine that employs an internal support mechanism, known as a mandrel, to achieve exceptional precision and accuracy in bending pipes while maintaining their structural integrity. The mandrel plays a crucial role in preventing deformation and ensuring the pipe retains its original shape throughout the bending process.
When bending a pipe without the assistance of a mandrel, the tube becomes vulnerable to collapse or distortion, resulting in issues such as ovality, wrinkles, or thinning of the pipe wall. By incorporating a mandrel into the process, these undesirable effects can be effectively prevented. The mandrel provides essential internal support that reinforces the pipe during bending operations and ensures a smooth and consistent bend while maintaining its structural integrity.
The mandrel pipe bending machine consists of several key components that work together to achieve efficient and high-quality bends. These components include the bender head, mandrel, clamping dies, pressure die, hydraulic system, and control panel.
- Bender Head: the key component of a pipe bending machine responsible for executing precise and accurate bends by securely holding the pipe in place and applying necessary force.
- Mandrel: a tool inserted inside the pipe to maintain its shape during bending.
- Clamping Dies: used to secure the pipe in place during bending. They hold the pipe firmly to prevent movement or slippage during the bending process.
- Pressure Die: exerts force on the exterior of the pipe, counteracting any buckling or distortion that may occur.
- Hydraulic System: the mandrel pipe bending machine is powered by a hydraulic system, which provides precise and controlled force and movement for the bending operation. This ensures accurate and consistent bending while allowing flexibility in adjusting parameters.
- Control Panel: allows operators to set specific bending parameters, such as the desired bend angle, radius, and speed. Operators can monitor and adjust the bending process through the control panel, ensuring optimal results.
How Mandrel Bender Works?
Mandrel bending is a method used to bend pipes or tubing without causing any deformations or wrinkles on the inner radius of the bend. This technique is commonly used in the automotive, aerospace, and construction industries, as well as in the manufacture of exhaust systems and furniture.
The process of mandrel bending involves inserting a mandrel, which is a solid metal rod, inside the pipe or tubing that needs to be bent. The mandrel is placed at the inner radius of the bend, and it supports the pipe or tubing from the inside, preventing it from collapsing or wrinkling during the bending process. The mandrel is usually made of steel, and it is available in various sizes and shapes to accommodate different pipe and tubing diameters and bend radii.
Look at below flow chart of how does a mandrel bender work, you will have a clear view.
